It features a 3\/4 inch mill diameter with a 0.06 inch corner radius, a 1-1\/2 inch length of cut, and a 4 inch overall length. The 40-degree helix angle and TiCN (Titanium Carbonitride) coating deliver improved wear resistance and cutting performance on ferrous and non-ferrous materials. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. It is sold individually and suited for use on CNC machining centers and manual mills by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for applications requiring a radiused corner rather than a sharp 90-degree edge, reducing stress concentrations in milled pockets, slots, and profiles. The micrograin carbide substrate supports tight tolerances and extended tool life in production and job-shop environments. Typical applications include contour milling, pocket milling, and finishing passes on steel, stainless steel, cast iron, and similar materials where corner geometry control is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating for improved hardness and wear resistance compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports precision tolerances and long tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC and manual spindle setups\u003c\/li\u003e\n\u003cli\u003eCorner radius tolerance of 0.0015 inches for repeatable radiused edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill compatible with standard 3\/4 inch collet chucks, end mill holders, and shrink-fit toolholders used on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the toolholder to prevent pullout under cutting loads. Verify runout with a dial indicator after tool installation and before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (0.3750 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12182671\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738531299634,"sku":"12182671","price":245.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47bbc5e04834a4cea47ee5f8c88e050d.jpg?v=1788800679","url":"https:\/\/voomisupply.com\/products\/accupro-12182671-corner-radius-end-mill-3-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
